Purpose:

    !>
    !> Compute a minimum-norm solution
    !>     min || A*X - B ||
    !> using the LQ factorization
    !>     A = L*Q
    !> computed by SGELQF.
    !>

Parameters
    M

    !>          M is INTEGER
    !>          The number of rows of the matrix A.  M >= 0.
    !>

    N

    !>          N is INTEGER
    !>          The number of columns of the matrix A.  N >= M >= 0.
    !>

    NRHS

    !>          NRHS is INTEGER
    !>          The number of columns of B.  NRHS >= 0.
    !>

    A

    !>          A is REAL array, dimension (LDA,N)
    !>          Details of the LQ factorization of the original matrix A as
    !>          returned by SGELQF.
    !>

    LDA

    !>          LDA is INTEGER
    !>          The leading dimension of the array A.  LDA >= M.
    !>

    TAU

    !>          TAU is REAL array, dimension (M)
    !>          Details of the orthogonal matrix Q.
    !>

    B

    !>          B is REAL array, dimension (LDB,NRHS)
    !>          On entry, the m-by-nrhs right hand side matrix B.
    !>          On exit, the n-by-nrhs solution matrix X.
    !>

    LDB

    !>          LDB is INTEGER
    !>          The leading dimension of the array B. LDB >= N.
    !>

    WORK

    !>          WORK is REAL array, dimension (LWORK)
    !>

    LWORK

    !>          LWORK is INTEGER
    !>          The length of the array WORK.  LWORK must be at least NRHS,
    !>          and should be at least NRHS*NB, where NB is the block size
    !>          for this environment.
    !>

    INFO

    !>          INFO is INTEGER
    !>          = 0: successful exit
    !>          < 0: if INFO = -i, the i-th argument had an illegal value
    !>
